Question

two number are in the ratio 7 : 3 if their difference is 20 find the number​

Answer 1

here, if x and y are in the ratio of 7:3 , and they have difference of 20 between them,x - y = 20 ;and that would make x/y = 7/3 ;i.e. x = 7y/3 ,taking that value of x , and putting it into first equation will give us,7y/3 - y = 20;so, 7y - 3y = 60 ;that is, 4y = 60 ;and that will give us, y = 15 . and so on, x = 35 ;So the answer is, 35 and 15 are the numbers that are in the ratio 0f 7:3 and have difference of 20.

Answer 2

Answer:

1) 35 and 2) 15

Step-by-step explanation:

take the given numbers in ratio as

7x and 3x

the difference is 20

So, 7x-3x=20

4x=20

x=20/4

x=5

first number=7x = 7×5=35

second number=3x = 3×5=15
